This study examines how rapid body colouration changes in Oryzias celebensis relate to aggressive behavior during male-male competition, finding that blackened markings signal aggression and deter attacks.

The effects of resource subsidy duration on detritus-based stream ecosystems: a stream mesocosm experiment

This study shows that subsidy duration affects fish competition and ecosystem functions in stream mesocosms, with prolonged subsidies leading to stronger monopolization by large fish.

Predation risk and resource abundance mediate foraging behaviour and intraspecific resource partitioning among consumers in dominance hierarchies

This study examines how predation risk and resource abundance affect foraging behavior and resource partitioning in masu salmon dominance hierarchies.
